Connection Handler

This is an abstract object type that cannot be instantiated.

Connection Handlers are responsible for handling all interaction with the clients, including accepting the connections, reading requests, and sending responses.

The following Connection Handlers are available:

These Connection Handlers inherit the properties described below.
